Silikon karbida hitam is a kind of silicon carbide, which is a hard hexagonal crystal generated by smelting quartz sand and petroleum coke at high temperature, and its density and hardness are very close to diamond, so it is usually also called diamond sand.

Black silicon carbide Introduction

1. Silikon karbida hitam adalah produk abrasif yang banyak digunakan, dengan ketahanan aus yang sangat baik, kekerasan tinggi, kepadatan tinggi, pengotor rendah dan keunggulan lainnya, commonly used in sandblasting and polishing, pemolesan, penggilingan gratis, membuat berbagai bahan abrasif, dll..
2. Due to its high hardness, density and stable crystal structure, black silicon carbide abrasive can be crushed and made into various size products, with coarse abrasive, black silicon carbide sand, black silicon carbide powder and other abrasive products ranging from 16 mesh to 5000 mesh available.
3. Silicon carbide powder is generally used for free grinding or sandblasting and polishing.

Black silicon carbide advantages

1. Silikon karbida due to chemical stability, konduktivitas termal yang tinggi, koefisien muai panas yang rendah, good wear resistance, in addition to abrasives, there are many other uses, for example: a special process to silicon carbide powder coated in the impeller of a hydraulic turbine or the inner wall of the cylinder body, can improve its wear resistance and extend the service life of 1 ke 2 times.
2. used to make refractory materials, heat shock, small size, light weight and high strength, good energy-saving effect. Low-grade silicon carbide (containing about 85% Sic) is an excellent deoxidizer, which can accelerate the speed of steelmaking, and facilitate the control of chemical composition, improve the quality of steel. In addition, black silicon carbide is also used in large quantities to make electric heating element silicon carbon rods.
